Such a shutter is slidably supported on the outer surface of the outer casing, and is operated to move between a position where the operation part is covered and a position where the operation part is exposed to the outside. It is possible.

However, the provision of the shutter increases the thickness of the electronic device, which may impair the portability of the electronic device. Although it has been proposed that the shutter is made of a metal plate material to reduce the thickness thereof, the shutter made of the metal plate material has a risk that a finger may slip easily and a smooth opening / closing operation may be hindered. There is.

Therefore, the present invention is proposed in view of the above-mentioned circumstances, and is an electronic device having a shutter for covering the operation portion, and the structure can be made thin, and the shutter can be moved. An object of the present invention is to provide an electronic device that can be operated smoothly.

[0010]

In order to solve the above-mentioned problems and achieve the above-mentioned objects, an electronic device according to the present invention has an outer casing formed of a metal plate material and an outer plate portion formed of the metal plate material. A shutter plate disposed on the outer side surface of the shutter plate, and a connecting member having a through hole provided on the shutter plate and a connecting pin inserted into a slit provided in the outer casing. A supporting plate formed of a metal plate material and attached to the connecting pin on the inner side of the outer casing, wherein the shutter plate is provided with the connecting member and the supporting plate with respect to the outer casing. The connecting member is mounted on the shutter plate so as to be slidable between a position that covers the operation portion provided on the outer side surface of the outer casing and a position that exposes the operation portion to the outside. Part and above And a coupling pin is being formed is integrally cast.

[0011]

In the electronic device according to the present invention, the operating member disposed on the outer side surface of the outer casing together with the connecting member and the supporting plate is covered with respect to the outer casing and the operating portion is located on the outer side. The shutter plate slidable over the position facing the shutter is formed of a metal plate material, and the connecting member has a portion mounted on the shutter plate and a connecting pin connected to the supporting plate. Since it is integrally cast and formed, the portion including these shutter plates can be made thin.
